Garry's Mod: Physics Sandbox Game for Steam

Garry's Mod is a physics sandbox game from Valve with no fixed campaign or set objectives. Instead, you use in-game tools and objects to experiment, build contraptions, and create your own activities. It suits players who enjoy open-ended play, construction, and user-created game modes.

Build, experiment, or make your own fun

Spawn objects and connect them to make creations such as cars, rockets, or catapults. If building is not your main interest, you can place characters in unusual scenes and experiment with the physics. The game can be played offline or online.

Community content and multiplayer modes

Steam Workshop adds community-made models, maps, contraptions, and tools. You can use selected items to expand your sandbox projects or try community-created modes. Examples include Trouble in Terrorist Town, where players take on investigation and criminal roles, and Prop Hunt, a hide-and-seek mode built around disguising yourself as objects.

Workshop content can broaden the experience, but some multiplayer servers and modes may require other games, including Counter-Strike: Source or Team Fortress 2. Check the requirements for the specific content or server you want to use.

Price and installation through Steam

Garry's Mod is a paid game. The source information describes Workshop items as free, but this does not make the game itself free to install.
